Deuteronomy 29:2-4 NIV

[2] Moses summoned all the Israelites and said to them: Your eyes have seen all that the LORD did in Egypt to Pharaoh, to all his officials and to all his land. [3] With your own eyes you saw those great trials, those signs and great wonders. [4] But to this day the LORD has not given you a mind that understands or eyes that see or ears that hear.
